Abstract
The choice of project solutions for systems of providing climatic conditions in premises, based on different types of renewable energy sources, was substantiated. The means proposed to solve project tasks, imply the use of the interaction between different stakeholders, the number of subsystems necessary for effective functioning in the open system, that is taking into account the synergetic effect. It was proved that the introduction of complex climate control and energy supply system will allow uniting the functions inherent to disparate engineering systems, and ensure the transformation and redistribution of various types of energy flows, which will minimize operating costs. The hierarchical structure of the problem of approval of alternative project solutions of the climatic systems based on the Analytic Hierarchy Process method was constructed, which allows obtaining a set of optimal variants. The application of the corresponding tool apparatus of Data Envelopment Analysis enables constructing a system of evaluation of the energy efficiency of projects of complex climatic control and power supply systems using different types of renewable energy sources. The functional intended to select the optimum variant of a project solution of the climate control and energy supply system was constructed. The proposed project solutions were examined from the position of determining the minimization of the total consumption of energy resources and operating costs of three alpha-stakeholders. The proposed indicator of relative integrated energy efficiency allows making an optimum choice of complex systems with disparate input and output characteristics
Highlights
In the field of project management, a portfolio is formed by consistent objective selection from the assigned totality of projects as homogeneous objects
Poor dynamics of decrease in power consumption volumes indicates a low level of production modernization in general
The aim of this study is the scientific substantiation of the choice of project solutions of the systems of providing climatic conditions in premises based on the use of different types of renewable energy sources
Summary
In the field of project management, a portfolio is formed by consistent objective selection from the assigned totality of projects as homogeneous objects. The further development of foundations for the formation of energy efficient systems for providing climatic conditions in premises based on the use of solar energy and energy of the environment is of important scientific and practical significance It is a relevant scientific and practical issue for the development of the power industry in the world, requiring further elaboration and solution. The complex of issues related to outlining the specifics of the implementation of project solutions of systems for ensuring climatic conditions in premises, based on renewable energy sources, requires in-depth analysis and methodological refinement It is becoming increasingly harder for power supply companies to determine a set of indicators of the effectiveness of the tools of project solutions needed to create long-term relationships in the market and to meet the needs of a customer
